This invention relates to deep well pumps and it is particularly adapted for utilizing gaseous iiuid under pressure as the motive fluid for operating the pump.

ln many oil fields natural gas is available so l prefer to introduce the natural gas under pressure and after it has served its purpose as the motive fluid, it may combine with the oil to render the oil buoyant and to be mixed with or absorbed by the oil to raise its gravity.- l do not wish to be limited, however, to the use of any particular gaseous motive fluid because the pump is adapted to be operated by diferent kinds of motive fluid and in any event, it has marked advan tages over the type of pump lmechanism which is operated by sucker rods connected to a walking beam. The chief advantage is that it can be placed in wells of any depth, thu's eliminating the disadvantages such as shut-downs and the like due to parting' of rods, etc.

The novelty of my invention will be apparent by reference to the following description in connection with the accompanying drawings in which:

pipes discharge into the valve casings 8 and 9 which have two outlets. The valve casing 8 has an outlet 10 which is connected to a 60 pipe or conduit 11 communicating with the top of a piston cylinder 12 in which is a piston 13 having a pump rod 14 connected to the plunger 15 of the working barrel 51 of the ordinary oil well pump. The working barrel and plunger is, of course, provided with the usual standing valve, traveling valve and lsand valve as will be well understood. The outlet. 17 in the valve casing 8 is connected to a pipe 18, in turn connected to the lower end of the piston cylinder 12 as at 19. The piston 13 is provided with an upstanding bar 20 carrying a rack 21 which drives a pinion 22 on the shaft 23, carried by the spider 24,

connected to the pump casing or cylinder 25.

The pinion 22, loose on shaft 23, is rigidly connected to a pinion 26 meshing with a rack 27 connected to the crank 28 of the crank shaft 29 which rotates in a clockwise direction and which has a crank 30 connected to 80 the stem 31 of a multiple valve 32 consisting of the three valve parts 33, 34 and 35. As

the fluid passes through the pipe 6 into the valve casing 8 with the valve parts in position to admit fluid to the under side of the piston 35 13,the upward movement of the piston 13 will impart an upward movement of the plunger 15 of the working barrel 51 and lift iuid above the working barrel into the cylinder 36 where it can flow out through the ports 37 (see Fig. 5) into the accumulating cylinder 38 and flow up through the ports 39 in the block 40 (see Fig. 9) above the valves and past the spiders 24 and 41 into the pump casing 25, up through the pipe 42 to the head 43 and out through pipe 44 (see Figures 2 and 3) As the piston 13 moves up, its rack 21 turns the pinion 22 causing pinion 26 to operate the rack 27 to turn the rock shaft 29 to operate the valve in casing 8 so that when the piston 13 reaches the limit of its up-stroke, the port 17 would communicate with the exhaust pipe through branch pipe 46 which discharges into the discharge pipe 42 to co-mingle with the oil. At the same' time, port 10 and pipe 6 communicate so that the motive fluid can now pass down through pipe 11 into cylinder 12 on top of piston 13 to affect a downstroke for the plunger 15. The motive fluid below the piston 13 now exhausts through valve casing 8, through branch pipe 47 to exhaust into pump casing25, the alternate up and down movements of the piston13 causing a continuous pumping operation of the plunger in the working barrel.

By reference to Figure 5 it will be observed that the working barrel is screwed to the boss 48 of the spider 40 and that it is connected to the cap 49 at the end of the cylinder 38 with the inlet 50 of the working barrel outside the cylinder 38. There are two working barrels and two pump operating mechanisms. I have described only one of them. The second working barrel is indicated at 16. It has a cylinder 12 with avpiston 13 connected to the valve casing 9 in substantially the same manner that the piston cylinder 12 is connected to the valve casing 8, the valve unit 34 being connected to the crank 52 of the crank shaft 29 which is operated through the medium of the pinion 53 and rack 54, driven by pinion 55 on shaft 23 through the medium of the rack 56 connected to the piston 13. The pipes 57 and 58, leading from the valve casing 9, communicate with the bottom and top ofthe cylinder 12 substantially like the pipes 11 and 18 communicate with the valve casing 8 and the cylinder 12, except that when the plunger in working-barrel 51 is moving up, the plunger in working barrel16 is mpving down and vice versa to cause a continuous flow of fluid through the pipe 42 at the top of the well. In othenwords, the two working barrels serve as l`a double pump mechanism.

The spiders 24 and41 are connected by the straps 59 and 60 within the cylinder 25V and the' whole mechanism suspended from the lower end of pipe 42 may be lowered into the Well in any appropriate manner.

The valve casings 8 and 9 may consist of ported liners in the block 40 and the block may be held in the cylinder by a ring 61 (see Fig. 8). Minor details of construction, however, are not so important, the invention residing more particularly in `thel arrangement of the pistons, valves and their co-operating mechanism in combination with the accumulating cylinder and the ported parts for delivering gaseous fluid into the piston-cylinders and exhausting it into the oil to be raised to the top of the well.

It is to be understood that the spider 24, Figure 6, is substantially like the spider 41, Figure 7, although it carries no gears as are shown in Figure 7. Therefore, the fluid will have a, free passage up through the casing 25.

1t is, therefore, to be understood that lchanges in form, proportion and minor details of construction can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What l claim and desire to secure by Letters-Patent is 1. A motor comprising two valve casings, each having a iuid inlet, two fluid supply outlets in spaced relation, and an intermediate exhaust, a valve in each casing movable therein, to communicate one of the supply outlets with the inlet and at the same time establish communication between the other outlet and the exhaust, a power cylinder for each valve casing having spaced ports connected to the supply outlets in the valve casing, power pistons in the cylinders between the inlet ports, gear racks outside the cylinders connected to the pistons, a main pinion in mesh with each rack, secondary pinions driven by the main pinions, racks meshing 'I with the secondary pinions, a crank shaft operated by the second mentioned racks and means connecting the valves to the crank shaft to cause the valve in one casing to uncover the exhaust to one of the sup ly outlets and establish communication between the inletY of the other valve casing and its complementary supply outlet and uncovering the exhaust port of the other valve casing to the remaining supply outlet.

2. A motor comprising two valve casings, each having a iuid inlet, two uid outlets in spaced relation and an exhaust outlet, a valve in each casing, each valve having -two valving portions and movable to positions to communicate one of the supply outlets with the inlet and at the same time establish communication between the other outlets, a power cylinder for each valve casing having spaced ports connected to the outlets in the valve casing, power pistons on the valves,

gear racks outside the cylinders connected second mentioned racks and means connecting the valves to the-crank shaft.

3. A motor comprising two cylinders, a piston 1n 'each cylinder, a piston rod conius the valve casings to the cylin ers to cause motive Huid to be alternately admitted to and exhausted from the` cylinders.

In testimony whereof I aix my si ature.
